Title (EN) COLOR WHEEL AND LASER PROJECTION DEVICE
(FR) ROUE DE COULEUR ET DISPOSITIF DE PROJECTION LASER
(ZH) 色轮和激光投影设备
Abstract:
(EN) A color wheel and a laser projection device. The laser projection device comprises a substrate and at least one fluorescent block (5). The substrate comprises a first annular part (3) and a second annular part (4); at least one fluorescent block (5) is arranged on the first annular part (3); the fluorescent block (5) is configured to be irradiated by laser and then emit fluorescent light of a corresponding pre-set wave band; the second annular part (4) comprises at least one filtering part (41); the filtering part (41) is configured to filter the fluorescent light; and an inner circumference of the second annular part (4) is not smaller than an outer circumference of the first annular part (3); or the outer circumference of the second annular part (4) is not greater than the inner circumference of the first annular part (3).
(FR) La présente invention concerne une roue de couleur et un dispositif de projection laser. Le dispositif de projection laser comprend un substrat et au moins un bloc fluorescent (5). Le substrat comprend une première partie annulaire (3) et une seconde partie annulaire (4) ; au moins un bloc fluorescent (5) est disposé sur la première partie annulaire (3) ; le bloc fluorescent (5) est configuré pour être irradié par laser et pour ensuite émettre une lumière fluorescente d'une bande d'onde prédéfinie correspondante ; la seconde partie annulaire (4) comprend au moins une partie de filtrage (41) ; la partie de filtrage (41) est configurée pour filtrer la lumière fluorescente ; et une circonférence interne de la seconde partie annulaire (4) n'est pas plus petite qu'une circonférence externe de la première partie annulaire (3) ; ou la circonférence externe de la seconde partie annulaire (4) n'est pas plus grande que la circonférence interne de la première partie annulaire (3).
(ZH) 一种色轮及激光投影设备,包括基板和至少一个荧光块(5)。基板包括第一环形部(3)和第二环形部(4),至少一个荧光块(5)设置在第一环形部(3)上,荧光块(5)被配置为接受激光照射后发出相应预设波段的荧光,第二环形部(4)包括至少一个滤色部(41),滤色部(41)配置为对荧光进行滤色,第二环形部(4)的内圆周不小于第一环形部(3)的外圆周,或者第二环形部(4)的外圆周不大于第一环形部(3)的内圆周。
